• Gasoline is very flammable. Avoid smoking
or bringing any flame or sparks near fuel.
Make sure to stop the engine and allow it cool
before refueling the unit. Select outdoor bare
ground for fueling and move at least 3m (10ft)
away from the fueling point before starting
the engine.
WARNING
• The Zenoah engines are lubricated by oil
specially formulated for air-cooled 2-cycle
gasoline engine use. If Zenoah oil is not
available, use an anti-oxidant added quality oil
expressly labeled for air-cooled 2-cycle engine
use. (JASO FC GRADE OIL or ISO EGC
GRADE)
• Do not use BIA or TCW (2-stroke water-cooling
type) mixed oil.
• Exhaust emission are controlled by the
fundamental engine parameters and
components (eq., carburation, ignition timing
and port timing) without addition of any
major hardware or the introduction of an inert
material during combustion.
• These engines are certified to operate on
unleaded gasoline.
• Make sure to use gasoline with a minimum
octane number of 89 RON (USA/Canada: 87AL)
■ INSTALLING CUTTING HEAD
1. While locking the gear shaft by inserting the
attached bar into the upper holder and the
gear box, loosen and remove the hexagon
bolt(left-handed)
2. Using the arbor bolt, screw in the cutting
head to the gear shaft over the holders.
Hand-tighten it securely.

RECOMMENDED MIXING RATIO
GASOLINE 50:OIL 1
• If you use a gasoline of a lower octane value
than prescribed, there is a danger that the
engine temperature may rise and an engine
problem such as piston seizing may
consequently occur.
• Unleaded gasoline is recommended to reduce
the contamination of the air for the sake of your
health and the environment.
• Poor quality gasolines or oils may damage
sealing rings, fuel lines or fuel tank of the
engine.
■ HOW TO MIX FUEL
1. Measure out the quantities of gasoline and oil to
be mixed.
2. Put some of the gasoline into a clean, approved
fuel container.
3. Pour in all of the oil and agitate well.
4. Pour In the rest of gasoline and agitate again for
at least one minute. As some oils may be
difficult to agitate depending on oil ingredients,
sufficient agitation is necessary for the engine to
last long. Be careful that, if the agitation is
insufficient, there is an increased danger of
early piston seizing due to abnormally lean
mixture.
5. Put a clear indication on the outside of the conta
container to avoid mixing up with gasoline or
other containers.
6. Indicate the contents on outside of container for
easy identification.
■ FUELING THE UNIT
1. Untwist and remove the fuel cap. Rest the cap
on a dustless place.
2. Put fuel into the fuel tank to 80% of the full
capacity.
3. Fasten the fuel cap securely and wipe up any
fuel spillage around the unit.
1. Select bare ground for fueling.
2. Move at least 10feet (3meters) away from the
fueling point before starting the engine.
3. Stop the engine before refueling the unit. At
that time, be sure to sufficiently agitate the
mixed gasoline in the container.
FOR YOUR ENGINE LIFE, AVOID;
1. FUEL WITH NO OIL(RAW GASOLINE) – It will
cause severe damage to the internal engine
parts very quickly.
2. GASOHOL – It can cause deterioration of
rubber and/or plastic parts and disruption of
engine lubrication.
3. OIL FOR 4-CYCLE ENGINE USE – It can
cause spark plug fouling, exhaust port blocking,
or piston ring sticking.
4. Mixed fuels which have been left unused for
a period of one month or more may clog the
carburetor and result in the engine failing to
operate properly.
5. In the case of storing the product for a long
period of time, clean the fuel tank after
rendering it empty. Next, activate the engine
and empty the carburetor of the composite fuel.
6. In the case of scrapping the used mixed oil
container, scrap it only at an authorized
repository site.
